I have had my Carlisle's since 99.. not too many miles, but last year at the end I noticed a large bump on left front.. So I traded them in two weeks ago for a new set of Goodyear Marathons.. Every time I asked the guy what the trade in value of the Carlisles were.. he smiled... I figured it was a pretty good deal.. a big ole smile for each junk tire.. not bad!!
I hope to be using those new tires some time in the future..
